The police force said in a statement: “Investigators believe the Stephenson family had just left the Kennedy Space Center in their rental vehicle and were attempting to navigate back to their rental house in Davenport at the time of the crash.

“GPS in the vehicle was instructing a “U-turn” at the intersection, most likely because of an earlier crash with road blockage on SR 407 -which was the original GPS route from the Space Center for their trip back to Davenport.”

A Foreign and Commonwealth Office spokesperson said: “We are supporting the family of four British people who have died in Florida.
